IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 222,239, dated December 2, 1879 application filed August 7, 1879.

To all whom it may concern:

Be it known that I, EDWARD L. BROWNING, of Mayfield, iirthe county of Graves and State of Kentucky, have invented a certain new and useful Improvement in Water-Elevators, of

which the following is a full, clear, and exact .description, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to an improvement on the water-elevator patented by Isaac Mayfield, dated September 26, 1871, No. 119,380; and

my improvement consists in constructing the hanging wheel with broad perforated flanges, as and for the purpose hereinafter set forth;

Figure 1 is an edge view of the wheel. Fig.

2 shows the wheel one-half in side elevation and one-half in section.

. Inthe Mayfield patent (No. 119,380) the endless chain is stretched by suspending in its lower bend a wheel whose whole bearing isupon the chain.

Myimprovement applies to this wheel, and

gives to it three advantages not found in this wheel as heretofore constructed: First, the y breadth of the flanges prevents the wheel becoming dislodged from the chaineven when the utmost violence is used in turning and re- Versing the chain; second, the perforations cause the agitation of the water as the wheel turns; third, the perforations provide means for the removal of the wheel fromthe bottom of the well when it may have been dropped by the breaking of the chain, a simple hook being engaged in one of the perforations.

A is the elevator-chain, and B the buckets.

These may be of any suitable construction.

My improvement does not relate to them.

0 is the wheel, having a hub, c. D D are the side flanges. The outer faces ofthe flanges may be parallel with each other, but their inner faces should incline somewhat outwardly, so that the flanges are thinner toward the periphery. Thus the inner faces will act as a 'butit is obvious that these dimensions form no essential feature of the invention, and may be changed without affecting its principle.

I claim as my invention- The hanging wheel 0, for water-elevators, havin g perforated flanges D D, substantially as set forth.

In testimony whereof I have hereunto set my hand this 25th day of July, 1879.

EDWARD L. nnowNiNG.
